Nice work. My only suggestion would be to get a soldering iron and solder all the connections. Twisted wire connections can cause all sorts of headaches down the road. Oh and heat shrink. it makes a nice water proof connection too. But still nice work.

Im considering winter tires too at the moment so cant help much there other than saying that from what ive seen while researching there are both 4 and 5 stud focus wheels kicking about on ebay. Mine (2005) is 5 stud, i think the 4 are from older modles. Someone correct me if im wrong.

No worries. Just been flicking through my manual and noticed that I have a fuse in my fusebox for what the manual says is a "Luggage compartment power point". Any idea what that might be or if it is an unconnected fuse (no wire on the drivers side that others have)

after some more investigation with a multimeter and pulling fuses it seems that the red wire is for the towing module. its on its own 20A fuse and is a permanent live 12v supply. Im sure i will be able to make use of that :)
